Yeah, when I started at Google, I had come from a game design background and hadn't written a line of production-level code in years. So it was kinda intimidating to be grouped in with a bunch of engineers who knew what they were doing. :) I think what helped me was that I eventually came to the realization that when people seem to know more about you, it's usually not that they're significantly smarter than you, it simply comes down to the fact that they just have spent more time with a certain technology than you have. In terms of practical advice, there's a lot of videos, books, TED talks, etc. about establishing a growth mindset. I might take a look at one of those, because I think that can really be helpful. (In fact, if any of you have good recommendations there, add 'em to this thread.)
